Text Network Connection

If you feel like the issue is related to your network connection, then make sure to test your connection by visiting Speedtest.net. A normal Up & Download speed, without interruption, is essential for a stable gaming experience. Especially your Ping should remain below 100ms.

Internet Connection Improvement Tips

Ensure to account for any VPN service that could be running on your system. Or turn off your VPN while in-game. Use an ethernet cable to ensure the best possible connection. If you have to use a Wifi connection, restart your router or modem if you haven't done this in a while, and reduce the number of devices connected to the same network.

Windows Settings > Network & Internet > VPN

End Network Intensive Tasks

Open up your Task Manager by searching for it in your Start Menu search. In the Performance tab, select Resource Monitor.

Task Manager > Performance > Resource Monitor

In the Network tab, open the Processes with network activity, and after a few seconds, you will see every process using your network connection. This might be your browser running in the background, steam, or a download bottlenecking your connection. I suggest you only end the processes you know won't break your operating system.

Resource Monitor > Network > Processes with Network Activity

Command Prompt

Next, open up your Command Prompt, by searching for CMD and hitting enter. Use the following commands:

ping google.com

This command will check your latency and packet loss to google's servers. If your ping is higher than 100ms or encounters any packet loss, you should make a few changes to your connection and follow the subsequent tweaks.

ipconfig /flushdns

This will flush and reset the content of your DNS resolver cache. Using this command can, in some cases, fix network-related issues with CoD Vanguard.

Change DNS Server Addresses

Verify your connection to your ISP and make sure that you are using a decent data plan. You can troubleshoot this step by switching your connection to your personal hotspot. When this is done, we will change your DNS server address in case the problem is still caused by your network connection. Open up your Control Panel by searching for it in your start menu search.

Make sure to View by: Category, and click on Network and Internet.

Next, click on Network and Sharing Centre, and here select your connection.

This will open up this window, containing some general information about your connection. Navigate to Properties and lastly, double-click the Internet Protocol Version 4. Select to Use the following DNS server addresses option, and as your Preferred DNS server, use : 8.8.8.8 and as you Alternate DNS server, use: 8.8.4.4.

This will for a lot of users fix network related issues when playing CoD Vanguard, as these are the official public DNS server addresses from Google, which are safe to use.

Update Network Adapter Driver

To further troubleshoot network related problems, I suggest updating your Network Adapter’s driver. To do so, search for Device Manager in your start menu search to open it up.

Expand your Network Adapters, right-click the one you are using and select Update Driver. Finally, click on Search automatically for drivers. This will take a second to download and install the latest Network Adapter driver.

Device Manager > Network Adapters > Update Driver

Windows Operating System Update

You should also make sure that your Windows version is up to date. Search for Update to open up your Check for Updates system settings window. Your Windows settings will open up. Click on Check for Updates, Download or Install Now, and restart your PC after making all these changes to your OS.

Disable 3rd Party Applications

Lastly, if you still get network-related issues, you most likely have software running on your system, hindering you from playing the game. To fix this, I suggest ending processes in your Task Manager of recently installed programs that can change your files or use up your available resources, such as OBS, Shadowplay, CCleaner, or Adobe applications, to troubleshoot which program is causing the issue.
